a) Draw a good 3-D drawing of a chair conformation of trans-1,2-dimethylcyclohexane.

b). Draw a good 3-D drawing of the chair ring-flipped conformation that you drew in (a).

c)

i. How many gauche-like interactions that involve methyl groups are there in the molecule that you drew in question (a) ?

ii. How many gauche-like interactions that involve methyl groups are there in the molecule that you drew in question (b) ?

iii. What is the energy difference in units of “gauche-like interactions” between the conformation in (a) and the conformation in (b)?

iv. What is ΔG for the equilibrium below in units of kJ/mol?
